IMPROVEMENT IN PORTABLE FOBGES.

Specification forming part of Letters Patent No. 217,265, dated July 8, 1879 application filed January 10, 1879.

i To all whom it may concern:

Be it known that I, AUGUSTUS BUROHFIELD,

. of Medina, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Portable Forges; and I do hereby declare the following to be a full, clear, and exact description of. thesame, reference being made to the accompanying drawings, forming a part of this specification, and in which-- v Figure l is a side elevation, partly in section; and Fig. 2, a plan view.

The object of my invention is the production of a portable forge mounted on a truck which shall be both simple in construction and operation, and especially adapted for blackand use my invention, I will now proceed todescribe the exact manner in which it is carried out.

In the drawings, A represents a low, strong, and durable fourwheeled truck, upon which is mounted a strong rectangular frame, B, provided with a platform, 0, and upon which and said frame the several parts of my improved forge and its appurtenances are mounted. E

representsa box secured upon the parallel and front cross-beams, b b, of the frame B. This box is provided near the top with a horizontal partition, a, dividing the box into two compartments, a a

F represents the fire-box of my improved forge, which is located in the upper compartment, a, of the box E, and is secured in said box by mortar or other suitable material filled in around the fire-box, so as to come nearly up or to the top of the fire -box, said mortar forming a suitable bed upon which to place the fuel, and also the necessary tools required for immediate use. This fire-box is provided with a removable grate, f, provided with a pivoted claw, f adapted to pass through the slot f in the fire-box, by means of which the grate is secured in position.

G represents the smoke-stack, provided with the hood G and parallel vertical slot 9, by which said smoke-stack is adapted to fit over the rear edge, e, of the box IE, and be thus firmly but removably secured thereto. 6 represents a platform secured to the front of frame B or box E, and upon which the operator stands while at work. H represents a seat removably secured to the front of the box E by the hooked projections h h engaging with the front thereof, said seat being provid ed with a foot-rest, It, all as clearly shown in Fig. 1 I I are upright posts secured upon the parallel longitudinal beams of the frame B, and connected by the upper and lower crossbeams t i, the lower cross-beam forming a support for the front portion of the tapering spout P, and in which the shafts J J for carrying the operating mechanism are mounted, shaft J being provided with a baudwheel, K, and cog -wheel is, which meshes with the driving gear-wheel k, operated by a crank, Z, all as clearly shown in Fig. 1.

M M represent upright posts secured to the rear cross-beam of the frame B, and in which the shaft 0' is journaled or mounted, said upright posts being connected by cross-beams m m, the lower cross-beam, m, forming a support for the fan-case N. This fan-case is formed of two semicircular sections, a a, the lower section, a, forming an extension of the tapering wind-spout P, which communicates with the tapering spout 6 leading to the air-chamber in the fire-box F.

0 represents the fan formed of the broad rectangular and straight fanblades 0 secured to the fan-shaft 0. These fan-blades are made of galvanized iron, polished smooth, and

are braced or supported on their rear sides by rods 0 secured centrally to the fan-shaft and to near the outer ends of the blades, as clearly shown in-Fig. 1, thus rendering the fan-blades simple in construction, while being strong, durable, and light, and not likely to get out of order.

The fan is designed as a substitute for bellows, and is revolved through the medium of the band B passing around band-wheel K and pulleyr on one end of shaft 0", said bandwheel receiving its motion through the gearwheels 7a 7a and hand crank Z. The straight fan blades, in connection with the fan case and tapering spout P, forming an extension of the lower section of the fan case, and conducting the currents of air produced by the fan to the air-chamber in fire-box, produce much steadier and more continuous air-currents, and which are therefore more efficient for blowing the fire.

S represents a vise, and S an anvil, each provided with a recess or slot, 5, on its under side, within which fits a lug, c, on the platform 0, by which said vise and anvil are secured to the platform when moving the forge from point to point, they being easily and readily detached and removed to the ground for immediate use, thus dispensing with any other vehicle for transporting them. '1 represents the water tank or box, secured on the platform 0 and provided with a tight fitting cover, t. U represents a coal or fuel box permanently fastened to the rear end of the truckframe and extending across the bed thereof. V represents the tongue or pole of the truck to which the horses are attached.

The lower compartment of the box E forms a receptacle or tool chest, which is provided with a door, E, all as clearly shown in Fig. 1. I am aware thatportable forges provided with fans the blades of which are supported or braced by rods on their rear sides and tapering spouts for conducting the air-currents produced by the fan to the fire-box are old.

I am also aware of the ordinary artillery or army forge mounted on trucks in a similar manner, and such I do not desire to claim, broadly, as my invention; but,

Having thus fully described my invention, \vhatI do claim, and desire to secure by Letters Patent, is-- As my improvement in portable forges, the arrangement herein described, upon the fourwhceled truck A and frame B, of the compartment-box E and fire-box F, with detachable drivers seat and smoke stack, the blast devices, the platform (J, with lugs c, anvil and 'vise, each provided with a slot, 8, Water-box,

and fuel-box, as described and shown.

AUGUSTUS BURGHFIELD.
